Her hand moved between her legs again for a moment. “I want to taste it,” she said before catching what she was doing as if her hand had betrayed her. “Fuck, I’m so horny.”
“Do you want me to leave you alone so you can get off?”
Robin blinked hard as she started up at him. “You would do that?”
“Sure, why not?” he asked with a shrug. It didn’t seem fair that he was the only one getting off.
“Can I watch the video, too?” she asked. He nodded. “And where are you going to be?”
“I don’t know. I guess I can go to my room until you’re done.”
“But you would still know I’m doing it.”
Thinking fast on his feet, he quickly countered with, “I don’t have to know.” He took a step towards the hallway. “I’m just going to go to my room for fifteen minutes and whatever happens, happens.”
“How do I know you won’t peek?”
“Because you might see me if I do,” he said, taking another step farther away. “Besides, if you sit in Mom’s chair like that, how much can I really see?”
Robin craned her neck around the side of the big, overstuffed chair and checked his line of sight as he moved to the hallway.
“See? I can’t see anything.”
“You sure?” she asked.
“Nothing at all,” he assured her.
“Set a timer,” she insisted.
After a detour back to the kitchen, Austin grabbed his Mom’s kitchen timer and wound the dial to fifteen minutes. He set it on the floor near the hallway. “There, now we can both hear it go off.”
“I’m not really going to do it,” she called out to him as he went to his room.
“I’ll see you in fifteen minutes,” he called back, knowing he would give her all the privacy she needed. He even made it a point to shut the door to his room loudly enough for her to hear.
As he paced back and forth in his room, he kept stroking his cock while thinking about his sister. Thinking about Robin touching her pussy felt good. He wondered why it didn’t feel wrong, all of it, everything that they were doing. Earlier, she had mentioned how it felt like none of this counted since he was her brother. He got that. While it felt risky because no one could ever know about it, it didn’t feel wrong. Strangely, it felt hotter because he was doing all this with Robin.
He glanced at the digital alarm clock on his dresser, using that to keep time just in case he couldn’t hear the ding of the wind-up timer. Wondering if she was really doing it drove him crazy. He thought about her tits, her nice ass, and how she had trimmed her pussy for a summer of wearing a bikini. Every bit of it made him harder and more excited. None of it made him feel guilty or wrong.
He had a couple of old Penthouse and Hustler magazines hidden beneath his mattress. He considered pulling one out while he waited before realizing he didn’t need it. The idea of his sister masturbating to his video was more than enough inspiration to get him worked up. After a lifetime of never really getting along with her, this all felt very cool. For once, he didn’t feel like her “little brother.” He felt like something closer to a man.
The timer dinged. He let go of his very hard prick and swung open the door to his bedroom. He didn’t announce his return. Either she had heard the timer or she hadn’t. A part of him hoped she hadn’t heard it.
